Stress Relieving Services
Our firm specializes in providing world-class Stress Relieving Services. These services deal with the reduction of stresses in particular structure so that it can be protected from the dimensional changes. We have installed highly advanced machines and other tools to ensure successful execution of these services. Furthermore, clients' requirements are followed while executing these services so as to gain their optimum satisfaction. Our Stress Relieving Services are highly appreciated by customers owing to their high reliability.
Stress relieving is carried out on metal products in order to minimise residual stresses in the structure thereby reducing the risk of dimensional changes during further manufacturing or final use of the component.
Typically, the parts that benefit from stress relieving are large and complex weldments, castings with a lot of machining, parts with tight dimensional tolerances and machined parts that have had a lot of stock removal performed.
Stress relieving is done by subjecting the parts to a temperature of about 75 Ãƒâ€šÃ‚ºC (165 Ãƒâ€šÃ‚ºF) below the transformation temperature,line A1 on the diagram, which is about 727 Ãƒâ€šÃ‚ºC (1340 Ãƒâ€šÃ‚ºF) of steelÃƒ¢Ã¢â€š¬Ã¢â‚¬thus stress relieving is done at about 650 Ãƒâ€šÃ‚ºC (1202 Ãƒâ€šÃ‚ºF) for about one hour or till the whole part reaches the temperature. This removes more than 90% of the internal stresses. Alloy steels are stress relieved at higher temperatures. After removing from the furnace, the parts are air cooled in still air.
